The present invention relates to a nursery chair and comprises among its objects the provision of a chair of this character which will fold into a minimum of space; the provision of a chair which is easily foldable and yet is;not readily operable by a child sitting therein; to provide in a chair of the character indicated readily detachable means for supporting collapsible and destructible containers; to provide a chair of the character indicated which, when the cover for the seat opening is put down into place, will have quite the appearance of an ordinary chair; to provide a chair which is simple and inexpensive to manufacture, may be sold at a reasonable price, and yet will be adapted for various uses; and such further objects, advantages and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. The present invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawings, and, while I have shown therein what is now considered the preferred embodiment of this invention, I desire this disclosure to be understood as illustrative only and not as limiting my invention.

In the drawings annexed hereto and form ing a part hereof, Fig. 1 is a front elevation of my new construction; Fig. 2 is a side elevation of the same; Fig. 3 is a fragmentary side elevation of this chair in part- 5 ly folded condition;'Fig. 4 is a perspective view of a guard which is attachable to and detachable from the seat of the chair; Fig. 5 is a perspective view of a, saddle which is attachable to and detachable from the rear portion of the seat of the chair and may be adjusted forwardly and rearwardly to vary the size of the opening therein; Fig. 6 is a perspective view of a ring which is insertable into the hole in the seat of the chair and which serves to hold the collapsible container in distended condition; Fig. 7 is a rear edge view of a portion of the chair seat, taken in the direction indicated by the arrows on line 7-7, Fig. 8; Fig. 8 is a plan 0 view of a portion of the chair seat intended upper cross bar of the loop 2 is provided y with portions which are reduced in width and about which the eyes 6 lit. These eyes andl reduced portions cooperate to hold this upper cross bar in proper position laterally of the chair. The upper cross bar of the Y loop 1 is placed Within the hooks7 so that the parts will be held in properly assembled relation to support the seat 4. Pivotally mountedy on the loop 2 is a latch 8 whose purpose will be referred to hereinafter.

The seat of the chair is provided substantially centrally with an opening which extends therethrough and which, as illustrated most clearly at 9 and l0 in Fig. 8, has a stepped wall, that is, vthe opening is of decreasing diameter from the top towards the bottoinand is provided with a plurality of shoulders. The trap door 11 is provided at itsI rear edge with an extension 12 which fits within an opening in the upper portion of the seat 4. This extension l2 is slotted in a plane parallel to they fiat upper surface of the trap-door and about midway between its two faces. Nails 13 are driven into the seat 4 to form an axis for the trap door 11 to turn about. The slot in the rear edge of the extension 12 is brought into registry with these nails 13 and then the trap door is shoved untilv the nails are approximately at the inner extremity of this slot. A wedge 14 is then glued into this slot to prevent the trap door 11 from being removed from the nails. These nails therefore form a portion of the hinge for` the trap door, the inner extremity of the slot in extension 12 forming the. other portion thereof. The rear portion of the opening in the seat extends entirely through the same to permit the extension 12 of the trap door to swing downwardly therein so that the trap door may occupy the position shown in Fig. 2. As illustrated in this figure the trap door 11 rests against the back 15 of the chair.

A U-shaped frame member 16 is pivoted at 17 to the seat 4 and has the back 15 secured between the extremities of the U-shaped member. The lower cross bar of this member cooperates with the latch 8 in preventing the chair back from swinging forwardly when it is not desired that it do so. A pair of posts 18 are pivoted tov the seat 4, as indicated at 19 and, as shown in Figs. 2 and 3, these remain substantially parallel at all times to thev `U-shaped frame 16:. The upper ends of members 18 are hingedly' connected to the arms 20 of the chair. These arms have pivotal connection at 21 with the arms of the U-shaped frame 16. Therefore, when the latch 8 is unlatched and the chair back is; pushed forwardly, the arms 20A also go forwardly and carry the upper ends of the posts 18 with them, as illustrated in Fig. 3.

Means for connecting the posts f8 to the arms 20; comprise brackets 22 provided with slots 23v for the reception of pivot bolts 24 whichpass through the slots 23 and the posts 18. The upper endv of each post 18 is provided with a notch 25- for the reception of a projection 26 formed on an arm of the bracket 27 which extends inwardly across the post 18, the bracket being secured to the' under side of the tray 28. The two brackets 27 serve as guiding means for the tray when the same is' placed upon the forward ends of the arms 20 and shoved backward-ly. It will therefore be seen that when the tray is put into the position shown in Fig. 3 and is shoved backwardly until the tray, posts 18, arms 20v and the back occupy the positions shown in Fig. 2, it will be i-mpossible toA remove the tray and therefore impossible for a child to release itself from the chair. In order toincrease the certainty that the child will remain in the cha-ir, the latch 8 is turned down into the position shown in Fig. 2 and this will then prevent the chair back from being moved forwardly so that the tray can be released.

The ring 302 is provided with anr inwardly and downwardly directed flange 31 designed to overlap the upper edge of thev containers which are placed in the detachable conical shaped waterproof bag 32. This bag is provided with a stiften-ing ring at its upper edge as indicated at 33. This ring rests upon the shelf 9 and supports the bag 32 in place as illustra-ted in Figs. 1 andv 2. `When the trapdoor 11 is closed, as illustrated in Fig. 3, it restsY upon the upper shelf 10 and fits entirely within this opening so that the upper surface of the seat is quite smooth. The: ring is provided with openings 34 and' 35, `as illustrated most clearly in Fig. 6. The saddle 36 isprovided with downwardly extending lugs 37 which are arranged in suitable openings 34 so that the size of the internal opening in the ring will be suitable for the child which is to use the chair. A suitable guard or shield 38 which is concavoconvex in form, as shown in Fig. 4, is provided with a forwardly extending arm 39 fromv which depends a lug 40 which is adapted to be inserted into the opening 35 of the ring 30 and into a corresponding opening-in the forward portion of the seat 4,l illustrated in dotted outline at 41 in Fig. 3. The ring 30, saddle 36 and guard 38 are all made of readily flexible rubber and therefore do not hurt the child, when being used.. Mention should probably also be made of the fact that when the ring 3@ is in use' it rests on the shelf l0 against which the trapt door rests when the chair is folded. is made of j-ust the right size to lit within the upper large portion of the opening through the seat of the chair. The sides of the gua-rd 38 are readily flexible sor that, thoughthey contact with the delicate skin of the inside of the childs legsy they do not chafe nor injure the chi-ld. Also, the uplper portion of the gua-rd rests against the abdomen of the child and therefore tends to prevent the child from leaning forwardly, though the armI 39 is not sufficiently rigid to prevent they guard 38 from being tilted forwardly under pressure.

Mention should have been made of the stops 42 which limit the backward motionl of the upper end of the posts 184. The slots 23? permit a more complete folding of the chair since the pivots-24 slide backwardl-y these slots when the chair is collapsed belyon'd a certain point. fact that the pivots 19' and 24 are not as far apart as the pivots 17 and 21. There is therefore quite a decided cooperationbetween the slots 23, pivots' 24', notches 25l and lug-s 26, in the hold-ing of the tray 28 in position.

Tt is of course understood' that the specific description of structure set forth above may be departed from without departing from The ring 30 ite This is` duey to the the spirit of my invention asset forth in this specilication and the appended claims.

vHaving now disclosed my invention, I claim:

1. A nursery chair including a seat and a retaining ring of resilient material, said seat having a stepped opening therethrough, the retaining ring being of a size and shape to fit in said opening and rest on a step thereof and having a downwardly extending flange around its inner edge to project below the step on which the ring rests'.

2. n a nursery chair, a seat having a substanti'ally centrali opening therethrough a saddle conforming approximately to the shape off the rear portion of the seat open# ing, said saddle having downwardly ex- Iizo tending lugs for adjustment purposes and said seat having openings to cooperate with said lugs in the forward and rearward adjustment of said saddle.

3. In a nursery chair, a seat having a substantially central opening therethrough, a retaining ring mounted in said opening and having its upper surface substantially flush with the upper surface of the seat, said ring having a laterally extending liange provided with adjustment openings and a saddle having downwardly extending lugs movable from some of said openings to others thereof for adjusting the eii'ective size of the seat opening.

4. In a nursery chair, a seat having an opening therethrough provided with a stepped wall, said opening having a rearward extension, and a closure member for said opening having a rearward extension pivoted in the rearward extension of the seat opening.

5. A guard for a nursery chair comprising an elongated concave fiexible article of readily flexible rubber provided with side walls extending in a direction approximately parallel to the longitudinal dimension of the guard, said guard having an arm extending outwardly away from the convex wall thereof.

In witness whereof, I hereunto subscribe my naine to this specification.
